what is THE ORIGIN OF bleach?

Invented in the 18th century by the Frenchman Claude Louis Berthollet, bleach took its name from the old village called Javel, located in Paris (now part of the 15th arrondissement).

Bleach was originally developed to help bleach laundry. It was adopted by washerwomen who found it to be a miracle product.

Its success was rapid, but it was only later that it was discovered to have other properties. In the 19th century, it was widely used as a disinfectant and to treat drinking water.

Today, bleach is available in liquid (bottles) or solid (tablets) form, Eurotab's flagship product since 1957.

What's the difference between bleach and chlorine?

Chlorine is a chemical element, whereas bleach is a chemical product that contains chlorine atoms.

In chemical terms, we use sodium dichloroisocyanurate (or NaDCC) in our chlorine formulas: it is therefore a chemical molecule containing chlorine atoms. Bleach, for its part, is a solution containing sodium hypochlorite (Na+ ClO-): it also contains chlorine atoms, present in the form of hypochlorous ion ClO-, responsible for the whitening power.

In fact, in the presence of water, NaDCC hydrolyses and releases a molecule of hypochlorous acid (HClO), which is responsible for disinfection. Depending on the pH, an acid-base equilibrium converts the chemical species HClO into the hypochlorite ion ClO-.

This is why bleach has historically been used for its bleaching power (ClO- species in solution), whereas chlorine is used for its disinfecting power (HClO species released when DCCNa comes into contact with water at acid pH). 

In short, bleach is most effective for whitening, while chlorine in the form of NaDCC is preferred for disinfecting.

WHAT ARE BLEACH TABLETS?

Bleach tablets are produced from a compacted concentrated powder containing sodium dichloroisocyanurate (or NaDCC). NaDCC is a biocidal active substance, also known as chlorine.

It is a powerful disinfectant that kills all bacteria, viruses and fungi, according to European standards:

Bactericide

KILLS BACTERIA

(EN 1276: suspension bactericide)

VIRUCIDE

KILLS VIRUSES

(EN 14476, surface virucide)

FUNGICIDE

KILLS FUNGI

(EN 13697: surface bactericide and fungicide)

NaDCC tablets are stable for at least 2 years and do not lose active chlorine over time, compared with liquid bleach (3 months).
